Galactic explosion offers astrophysicists new insight into the cosmos

Using data from the James Webb Space Telescope’s first year of interstellar observation, an international team of researchers was able to serendipitously view an exploding supernova in a faraway...

Reminder: Massive stars are not stars. They're binaries. Also, close binaries are not binaries. They're triple systems. (Moe & Di Stefano 2017; Tokovinin+2006: ui.adsabs.harvard.edu/abs/20… ui.adsabs.harvard.edu/abs/20…)

Replaced other figure. Updated. Thanks to @veresp for noting that I had missed a handful of higher-fluence events. The Fermi catalog puts GRB 221009A at 3.9e-2 ergs/cm^2

Seems ... improbable. Plot motivated by thinking about neutrino constraints, rates, and reported fluence of 2.9e-02 ergs/cm^2 (from gcn.gsfc.nasa.gov/gcn/gcn3/3…) Data for Fermi GRBs from heasarc.gsfc.nasa.gov/db-per… Maybe I did something wrong.
